What Is Force? Flashcards
is an influence that can change the motion of an object.
Force
can also be described intuitively as a push or pull.
Force ( 2 )
it is measured in the SI unit of newton ( N ) / represented by the symbol “ F “
Force ( 3 )
refers to the size or strength of the force. It is commonly expressed in newton (N) for Meter-Kilogram-Second (MKS) system, dyne (dyn) for Centimeter–Gram–Second (CGS) system and pounds (lbs) for Foot– Pound–Second (FPS) system. In the International System of Units (SI), newton is commonly used which is named after Sir Isaac Newton, an English physicist and mathematician.
Magnitude
points to where the object goes.
Direction
the location on where the force is applied.
Point Of Application
is the straight line passing through the point of application and is parallel to the direction of force.
Line Of Action
two types of forces
Contact force / Non-contact force
forces where objects touch or contact with each other.
Contact forces
a force given to a person or object by another person or object.
Applied Force
is the force acting against or opposite an object in contact with which makes the movement of the object slow down. ______ always opposes the motion of an object. Its symbol is written as Ff or simply a small letter f.
Friction Force
is the force applied to string, rope, chain or cable. Its symbol is FT or simply T.
Tension Force
forces where objects do not touch or contact with each other. These forces act over a zone or area called field.
Non-contact forces
is the force of attraction between two objects.
Gravitational Force
are forces exerted on a field of attraction or repulsion as in the
case of magnets and other magnetic materials.
Magnetic Force
the two types of poles in the magnetic force
North Pole / South Pole
is the attractive or repulsive interaction between any two charged
bodies.
Electric Force
The two types of charge in the electric force
Positive / Negative
it does not cause a change in motion.
Balanced Forces
Forces that cause a change in the motion of an object are ______
Unbalanced Forces
are not equal and in opposite direction.
Unbalaned Forces ( 2 )
is the sum of all forces acting on an object.
Net Force / Resultant Force
The force exterted by any surface on an object touching the surface is called ____
Normal Force
is the force needed to compress or extend a spring and other elastic object.
Spring Force
